Salt water for a few days, found out of the bubble water is black; for a few days and saline bubble, a total of ten days, global water is still black, there are chemical substances deposited in on the side of the plate. I do not know what it is, for the people
Estimated to be dyed, or from the board after the farmers market to buy wood. Personally think or do not use.
The board may be dyed in order to improve the appearance and the multi bubble several times, as long as it does not affect the use of what should not, with salt water has an antibacterial effect, can mold and flavor, anti cracking oil.
The principle is that the general chopping board has been used for a period of time, because most of the water is evaporated and is easy to crack. Salt contains a trace of Magnesium Sulfate, which has a strong moisture absorption. If the newly bought chopping board is soaked in salt water for a few days, then it can be used to maintain a certain amount of moisture, so that the chopping board will not produce a breach.The oil poured approach: mainly to protect the surface of saturated permeability block, in the future, there will be no oil again penetrate into the chopping block, keep chopping cleanliness, easy cleaning, oil stains.
With salt water bubble is to let the cell water loss, so that the wood fiber more closely, so cut on the above there is no trace of it, that is, by cutting, the use of points. As for the black stuff, it is the wood fiber, that is, things in the plant cells, such as the loss of green chlorophyll is black, is not toxic.There is nothing wrong with the things that come out of the wood, and the salt is not K, Na, I.
